James,
If you make copies off the current broadcasts,keep in mind they may have been edited for time,so sometimes something is just "missing" from the shows.
The originals ran about 22 minutes or so,but current sitcoms run about 18 minutes,and the old shows are edited down to make more room for commercials.
If you are old enough to remember watching those old black and white shows as first runs,you might recall they only had one commercial break in the middle of a half hour,instead of the two today.
I really noticed it on one Andy Griffith episode,something just jumped and didn't make much sense.That is when it hit me about the heavy editing for time,probably two or three scenes per episode and shorter intros and such.
I had read not too long before that about the time difference,about the time the Freinds cast got one million per episode was probably why brought it up in the article.
Dang it,now I want to go out and buy the sets!
Regards,
